Abstract
Description
- This invention relates generally to tracking and billing for time that a wireless communication device is communicating with a telematics unit. In particular, the invention relates to tracking time that a short-range wireless semiconductor device is in short-range wireless connection with a telematics unit and billing for that connection time.
- The opportunity to personalize features in a mobile vehicle is ever increasing as the automobile is being transformed into a communications and entertainment platform as well as a transportation platform. Many new cars will be installed with some type of telematics unit to provide wireless communication and location-based services. These services may be accessed through interfaces such as voice-recognition computer applications, touch-screen computer displays, computer keyboards, or a series of buttons on the dashboard or console of a vehicle.
- Currently, telematics service call centers, in-vehicle compact disk (CD) or digital video display (DVD) media, web portals, and voice-enabled phone portals provide various types of location services, including driving directions, stolen vehicle tracking, traffic information, weather reports, restaurant guides, ski reports, road condition information, accident updates, street routing, landmark guides, and business finders.
- For example, traffic and driving directions may be accessed through a voice portal that uses incoming number identification to generate location information based on the area code or prefix of the phone number, or to access location information stored in a user's profile associated with the phone number. Users may be prompted to enter more details through a voice interface. Other examples are web and wireless portals that offer location-based services such as maps and driving directions where the user enters both start and end addresses. Some of these services may have a voice interface.
- Some users want to interface their personal portable wireless communication devices, such as cellular phones or PDAs with the telematics unit in order to access some of the telematics system features. With such an interface, the user can place their cell phone on the passenger seat and use the speaker system in the vehicle to talk on the cell phone. This interface also allows the user to access other the telematics features including dialing numbers one digit at a time, using a phonebook or contact list, accessing calendar appointments, storing data such as contact information, bookmarking radio stations and more.
- Currently, a user can pay the up-front costs required to install the software and hardware for a permanent system to support a short-range wireless connection between the portable wireless communication device and telematics unit. The user pays up-front, since there is no currently established method to monitor the time usage of the short-range wireless connection with a telematics unit. If the user infrequently utilizes the short-range wireless connection feature, the cost for each usage is expensive for the user.
- It is desirable, therefore, to offer the user a short-range wireless connection as a feature available within the software and hardware of the telematics unit that overcomes these and other disadvantages.
- One aspect of the present invention provides a method of tracking short-range wireless communication in a vehicle. The method includes tracking a total usage time of a short-range wireless connection between a telematics unit and a portable wireless communication device, sending the tracked total usage time from the telematics unit to a call center via a wireless connection and generating a usage bill at the call center based on the total usage time.
- Another aspect of the present invention provides a system for tracking short-range wireless communication in a vehicle. The system includes means for tracking a total usage time of a short-range wireless connection between a telematics unit and a portable wireless communication device, means for sending the tracked total usage time from the telematics unit to a call center via a wireless connection, and means for generating a usage bill at the call center based on the total usage time.
- A third aspect of the present invention provides computer readable medium storing a computer program including computer readable code operable for tracking a total usage time of a short-range wireless connection between a telematics unit and a portable wireless communication device, sending the tracked total usage time from the telematics unit to a call center via a wireless connection, and generating a usage bill at the call center based on the total usage time.
- The foregoing and other features and advantages of the invention will become further apparent from the following detailed description of the presently preferred embodiment, read in conjunction with the accompanying drawings. The detailed description and drawings are merely illustrative of the invention rather than limiting, the scope of the invention being defined by the appended claims and equivalents thereof.

The radio network controller interfaces with service nodes and gateways to mediate with the network service providers.
- As used herein, the term “calibration” means configuring a device to perform in a desired fashion. In one embodiment, calibration includes selectively enabling or disabling communication between portable
wireless communication device 182 and short-rangewireless semiconductor device 136. In one embodiment, calibration includes selectively setting a billing state. A billing state includes a pre-pay state, a post-pay state and an unlimited use state in one embodiment. - During stage S204, the short-range
wireless semiconductor device 136 at thetelematics unit 120 detects a wireless transmission signal from the portablewireless communication device 182 in response to the user opening a communication channel via one or morewireless carrier systems 140, one ormore communication networks 142, and/or one ormore land networks 144. The short-rangewireless semiconductor device 136 establishes a short-range wireless communication with portablewireless communication device 182 in response to the detection of the wireless transmission signal. The short-rangewireless semiconductor device 136 transmits a detection signal to theprocessor 122 in thetelematics unit 120 after recognizing a transmission signal from the portablewireless communication device 182. In one embodiment, the short-range wireless connection is established within a distance of 10 meters between the portablewireless communication device 182 and thetelematics unit 120. - During stage S206, the
telematics unit 120 initiates tracking of a short-range wireless connection between the portablewireless communication device 182 and thetelematics unit 120 responsive to short-range wireless semiconductor device detecting the wireless communication signal. - The software and hardware in the
telematics unit 120 is configured to automatically initiate the tracking of the short-range wireless connection between the portablewireless communication device 182 and the short-rangewireless semiconductor device 136. In one embodiment, the user may select to over-ride tracking if any of the services supported by thetelematics unit 120 are not required. In another embodiment, the user pushes a button on thetelematics unit 120 to over-ride the tracking. - In another embodiment, the software and hardware in the
telematics unit 120 is configured to automatically prevent tracking of the short-range wireless connection between the portablewireless communication device 182 and the short-rangewireless semiconductor device 136, unless the user wants to use one or more of the services supported by thetelematics unit 120. In this embodiment, the user selects to track the connection between the portablewireless communication device 182 and thetelematics unit 120. In another embodiment, the user pushes a button on thetelematics unit 120 to select to initiate the tracking. - If the tracking is not initiated, the user will not be able to access the services offered by the
telematics unit 120. If a portablewireless communication device 182 is not calibrated with thetelematics unit 120, the short-rangewireless semiconductor device 136 does not recognize the transmission signal from the portablewireless communication device 182. In this case, the user will not be able to access the services supported by thetelematics unit 120. - During stage S208, the
telematics unit 120 tracks a total usage time of the short-range wireless connection between thetelematics unit 120 and the portablewireless communication device 182 based on the initiation of tracking during stage S206. Thetelematics unit 120 tracks event usage time of the ongoing short-range wireless connection session. The event usage time is the number of minutes that the short-range wireless connection is open and using the services of the telematics system. When the short-range wireless connection session is terminated,telematics unit 120 adds the number of minutes in the event usage time to the number of minutes in the total usage time, wherein the sum forms an updated total usage time. The total usage time is the sum of all the event usage times tracked since the last time the total usage time was reset to zero, as described below with reference to stage S216. In one embodiment, the total usage time is the sum of all the event usage times tracked before a given short-range wireless connection session. The method of tracking the total usage time is described in detail below with reference tomethod 300 ofFIG. 3 . - During stage S210, the
telematics unit 120 stores the total usage time in the in-vehicle memory 128 of thetelematics unit 120. - During stage S212, the
telematics unit 120 initiates a wireless connection between thetelematics unit 120 and thecall center 170. In one embodiment, thetelematics unit 120 initiates a wireless connection between thetelematics unit 120 and thecall center 170 via the one or morewireless carrier systems 140, one ormore communication networks 142, and/or one ormore land networks 144 not including the short messaging service network. - In another embodiment, the
telematics unit 120 initiates wireless short messaging service (SMS) connection between thetelematics unit 120 and thecall center 170. The wireless short messaging service networks are based on GSM, code division multiple access (CDMA), and time division multiple access (TDMA) standards. The wireless short messaging service network, which is included in the one or morewireless carrier systems 140, one ormore communication networks 142, and/or one ormore land networks 144, provides the mechanisms required to find the destination station, such as thecall center 170, and to transport short messages between the short messaging service centers (SMSCs) and mobile switching centers to access thewireless carrier systems 140. Short messaging service has several input mechanisms to interconnect with different message sources and destinations. - A distinguishing characteristic of short messaging service is that the
telematics unit 120 is able to transmit a short message at any time, independent of whether another voice or data call is in progress. Short messaging service uses out-of-band packet delivery and low-bandwidth message transfer. Short messaging service guarantees delivery of the short message. Temporary failures are identified, and the short message is stored in the short messaging service centers until the destination receiver device becomes available. - During stage S214, the
telematics unit 120 sends the tracked total usage time to thecall center 170 via the wireless connection established during stage S212. In one embodiment, the sending the tracked total usage time is responsive to initiating a wireless short messaging service (SMS) connection between thetelematics unit 120 and thecall center 170 that occurred during stage S212, and the tracked total usage time is sent to thecall center 170 over the established short messaging service network. Otherwise, the tracked total usage time is sent to thecall center 170 via the one or morewireless carrier systems 140, one ormore communication networks 142, and/or one ormore land networks 144 not including the short messaging service network. - In one embodiment, sending the tracked total usage time is responsive to triggering a vehicle data upload request from the
telematics unit 120 to thecall center 170. As the term is used herein, a vehicle data upload is a connection initiated by thetelematics unit 120 to thecall center 170, responsive to at least one trigger. A trigger is any event that has been predetermined to result in taking of predetermined actions. For example, a trigger may be traveling a certain distance, a certain number of ignition cycles, a predetermined GPS-determined location, the setting of a diagnostic trouble code (DTC), or the passage of time, such as 30 days. In this embodiment, the trigger is the passage of time since last generating a usage bill as described below with reference to stage S218, a specific date associated with generating a usage bill, or a certain number of ignition cycles. A usage bill details the charges to a user for the total usage time of a short-range wireless connection between thetelematics unit 120 and the portablewireless communication device 182 to utilize the services of the telematics system. - During stage S216, the
telematics unit 120 sets the total usage time stored in the in-vehicle memory 128 of thetelematics unit 120 to zero responsive to the sending of the tracked total usage time in stage S214. - During stage S218, the
call center 170 generates a usage bill based on the total usage time sent to thecall center 170 during stage S214. Thecall center 170 receives the total usage time and multiplies the minutes of the total usage time by a preset billing rate to obtain the charge for the total usage time. In one embodiment, thecall center 170 adds any taxes, fees or other billable charges as required by a contract or regulations associated with the usage bill. In this embodiment, the billing occurs periodically. - In another embodiment, the user is periodically billed a flat rate for the service of obtaining telematics system features with the portable
wireless communication device 182, if the service was used during that period. In an alternative embodiment, the user is periodically billed a flat rate for the service, whether or not the service was used. In this latter embodiment, the tracking of total usage time is not required. - In one embodiment, the carrier for the portable
wireless communication device 182, or a third party facility, handles the billing rather than thecall center 170. In that case, a wireless short messaging service (SMS) connection is established between thetelematics unit 120 and the carrier for the portablewireless communication device 182 for the carrier to verify the connection between the portablewireless communication device 182 and thetelematics unit 120. In one embodiment, thetelematics unit 120 sends the event usage time to the carrier. In another embodiment, the carrier tracks the total usage time after thetelematics unit 120 establishes a wireless short messaging service (SMS) connection with the carrier and prompts the carrier to begin tracking. -
FIG. 3 illustrates a flowchart representative of a first embodiment of amethod 300 of tracking the total usage time in accordance with the present invention. Thetelematics unit 120 has stored in computer readable medium at least one computer program, which includes computer readable code to perform the operations described with reference tomethod 300. - During stage S302, the
telematics unit 120 stores an initiating time and an initiating date associated with initiating the tracking of the short-range wireless connection that occurred during stage S206 ofmethod 200 inFIG. 2 in the in-vehicle memory 128. During stage S304, thetelematics unit 120 receives a wireless end-communication signal from the portablewireless communication device 182. The short-range wireless connection between the portablewireless communication device 182 andtelematics unit 120 is terminated when the portablewireless communication device 182 ends transmission to an external receiver over the one or morewireless carrier systems 140, one ormore communication networks 142, and/or one ormore land networks 144. - The communication between the portable
wireless communication device 182 and the external receiver is terminated by transmission of the wireless end-communication signal from the portablewireless communication device 182, which is also received by the short-rangewireless semiconductor device 136. The short-rangewireless semiconductor device 136 transmits the end-communication signal to theprocessor 122 in thetelematics unit 120. Theprocessor 122 establishes a terminating time and a terminating date when the end-communication signal is received from the short-rangewireless semiconductor device 136. Specifically, the terminating time and the terminating date are the time and date that the end-communication signal received at thetelematics unit 120. - In one embodiment, the user has the option to terminate tracking of the event usage time of the short-range wireless connection after obtaining the desired telematics services, but before terminating the communication with an external receiver via one or more
wireless carrier systems 140, one ormore communication networks 142, and/or one ormore land networks 144. In this case, the user may push a button to terminate the tracking and to deliver an end-communication signal to thetelematics unit 120. In this embodiment, the end-communication signal may not be wireless and can be input directly to thetelematics unit 120. - During stage S306, the
telematics unit 120 stores the terminating time and the terminating date, which were established responsive to receiving the wireless end-communication signal in the in-vehicle memory 128. - During stage S308, the
telematics unit 120 determines an event usage time based on the initiating time, the initiating date, the terminating time and terminating date. Specifically, thetelematics unit 120 retrieves the initiating time on the initiating date and the terminating time on the terminating date stored in the in-vehicle memory 128 and calculates the number of minutes that passed between the initiating and the terminating. The calculated minutes equal the event usage time. In one embodiment, thetelematics unit 120 calculates the number of minutes and seconds to form the event usage time in minutes and seconds. - During stage S310, the
telematics unit 120 adds the event usage time to the total usage time in order to update the total usage time responsive to determining the event usage time. -
FIG. 4 illustrates a flowchart representative of a first embodiment of amethod 400 of monitoring call initiation location according to the present invention. The initiation location includes the longitude and latitude of theMVCU 110 when the short-range wireless connection is initiated. Thetelematics unit 120 has stored in computer readable medium at least one computer program, which includes computer readable code to perform the operations described with reference tomethod 300. - During stage S402, the
processor 122 requests a position fix from aGPS unit 126 in thetelematics unit 120 responsive to initiating the tracking of the short-range wireless connection that occurred during stage S206 inmethod 200 ofFIG. 2 . During stage S404, theprocessor 122 in thetelematics unit 120 receives the initiating position fix responsive to the request for a position fix from a GPS unit that occurred during stage S402. During stage S406, theprocessor 122 stores the initiating position fix with the initiating time and the initiating date in the in-vehicle memory 128 of thetelematics unit 120. The initiating time and the initiating date were stored in the in-vehicle memory 128 of thetelematics unit 120 during stage S302 as described above. - During stage S408, the
telematics unit 120 sends the initiating position fix, the initiating time and the initiating date to thecall center 170 via a wireless connection. - In one embodiment, the
call center 170 requests the initiating position fix, the initiating time and the initiating date from thetelematics unit 120 based on a request by a user for the initiating position fix of theMVCU 100 for a specific short-range wireless connection. A user may request the initiating position fix of theMVCU 100 to dispute a roaming charge from the wireless carrier provider. - In another embodiment,
telematics unit 120 sends the initiating time and the initiating date from the in-vehicle memory 128 responsive to triggering a vehicle data upload from thetelematics unit 120 to thecall center 170, as described with respect to stage S214. In one embodiment, the trigger is the passage of time since last generating a usage bill, a specific date associated with generating a usage bill, or a certain number of ignition cycles. - The wireless connection can be established as a wireless short messaging service (SMS) connection. Alternatively, the wireless connection can be established over the one or more
wireless carrier systems 140, one ormore communication networks 142 and one ormore land networks 144 which do not include the short messaging service network. In one embodiment, the wireless connection is the same wireless connection used during stage S214 to send the tracked total usage time to thecall center 170. - During stage S410, the
call center 170 stores the initiating position fix, the initiating time and the initiating date in one or morecommunication services databases 176 at thecall center 170. In one embodiment, the initiating position fix, the initiating time and the initiating date are stored for a limited time and then deleted. The limited time may be three months. - While the embodiments, of the invention disclosed herein are presently considered to be preferred, various changes and modifications can be made without departing from the spirit and scope of the invention. The scope of the invention is indicated in the appended claims, and all changes that come within the meaning and range of equivalents are intended to be embraced therein.
